I am getting this issue after i had upgraded the server and ruby is updated with 2.7 now…
Can someone help in fixing…i tried gem update --system but got an error
ERROR: Your RubyGems was installed trough APT, and upgrading it through RubyGems
itself is unsupported. If you really need the latest version of RubyGems (tip:
you usually don’t), then you need to install RubyGems (and Ruby) manually,
maybe using tools like ruby-install, rvm, etc.
